How does that vz network extender work? If it requires broadband I'm assuming it has your phone use voip or at least it converts your normal cell signal into voip to put into the vz network.
Honestly with how highly they seem to regard their network coverage, I would think they would give heavy discounts on those extenders. they are expensive.
It is a miniature (low strength) cell phone tower. It simply allows your phone to connect to it rather than an external antenna and then sends the info to VZW network via your ISP. So it will work with all VZW phones.
That's relative... the OP is spending $50/month on the phone, so this would pay for itself in 5 months, that's not really expensive consider the saving over a two year contract. You also have to remember that they are ONLY charging for the hardware (i.e. they are no additional usage fees associate with it). So you have to figure that SEVERAL people are likely to do as the OP (i.e. cancel home service and go strictly cell) so the added network load(s) that this will bring need to be compensated for. Also keep in mind that 'Coverage Maps' are ONLY ever an estimate (and a loose one at that) of OUTDOOR coverage. Carriers make NO claims or guarantees of indoor coverage and MANY people see decreased signals within their homes.
It's also still WAY cheaper than Skype or any other VIOP service (e.g. through your cable company) and has the added convenience of allowing you to truly have only 1 number.
